Power and Cooling Considerations for Power-over-Ethernet (PoE)

Power-over-Ethernet (PoE) can cut costs by enabling, for the first time, the deployment of a single Ethernet cable for simultaneous access to both power and data. However, lack of a power and cooling plan to support the PoE implementation can result in unanticipated downtime. This paper illustrates which power and cooling factors to consider when safeguarding a PoE investment.
